Hex Nut
hexagonal nut is a general-purpose fastener with a standard hexagonal outer contour, a metric machine threaded inner hole, and a flat end face. The surface is typically treated with galvanizing, and common sizes range from M3 to M30. Available materials include low-carbon steel, medium-carbon steel, alloy steel, 304 stainless steel, and 316 stainless steel. Surface treatments are diverse, including environmentally friendly blue-white zinc plating, color zinc plating, black zinc plating, hot-dip galvanizing, Dacromet coating, natural stainless steel finish, and stainless steel passivation. They are widely used in steel structure connections, machinery assembly, automotive parts assembly, building construction fixings, and general hardware fastening.
